Abstract
A single carrier method uses a user device which transmits at least an upstream control channel. The user device includes: means for preparing channel state information indicating a downlink radio propagation condition; and transmission means for transmitting an upstream control channel containing channel state information in a predetermined dedicated band when no radio resource is allocated for transmission of the upstream data channel. The transmission means transmits a predetermined number of unit blocks for each slot cycle. When the system bandwidth is greater than a predetermined value, a set of predetermined number of factors multiplied on a predetermined number of unit blocks containing the same content in the same slot expresses an orthogonal code sequence while a predetermined number of symbol elements constituting one unit block expresses at least a part of the channel state information.
Description
Technical field
The present invention relates to mobile communication system, base station apparatus, user's set and method by the ul transmissions control channel.
Background technology
Current, the standardisation bodies 3GPP of W-CDMA is carrying out UTRA or Long Term Evolution (the LTE:Long Term Evolution) systematic research of evolution.The LTE system is the system of the subsequent communication mode of Wideband Code Division Multiple Access (WCDMA) (W-CDMA) mode, high-speed downlink packet access (HSDPA) mode, High Speed Uplink Packet access (HSUPA) mode etc.In the LTE system, use OFDM (OFDM:Orthogonal Frequency Division Multiplexing) mode for down link, for up link, use single-carrier frequency division multiple access (SC-FDMA:Single-Carrier Frequency Division Multiple Access) mode (to this, for example, with reference to 3GPP TS36.211 (V8.0.0), Sept 2007).
In the LTE system, in down link and up link, distribute more than one Resource Block to communicate to user's set (UE:User Equipment).Resource Block is shared in intrasystem a plurality of user's sets.The base station determines which the user's set distributes resource blocks (this processing is known as scheduling) in a plurality of user's sets in the subframe (Sub-frame) of each 1ms in LTE.Subframe also can be known as transmission time interval (TTI).And then, subframe comprises a plurality of (for example two) time slot.In down link, the base station sends shared channel to the user's set of selecting by scheduling by more than one Resource Block.This shared channel is known as downlink physical shared channel (PDSCH:Physical Downlink Shared Channel).In up link, the user's set of selecting by scheduling sends shared channel to the base station by more than one Resource Block.This shared channel is known as ascending physical signal shared channel (PUSCH:Physical Uplink Shared Channel).
In the communication system of using shared channel, need to signal (notice) in each subframe which user's set is distributed above-mentioned shared channel.This signal notifies employed control channel to be known as downlink physical control channel (PDCCH:Physical Downlink Control Channel) or descending L1/L2 control channel (DL-L1/L2Control Channel) in LTE.For example can comprise down dispatch information (Downlink Scheduling Information) among the physical downlink control channel PDCCH, send to confirmation (ACK/NACK:Acknowledgement information), uplink scheduling information (Uplink Scheduling Grant), overload indicator (Overload Indicator), transmission power control commands bit (TCP Command field bit: Transmission Power Control Command Bit) etc.
Fig. 1 represents the employed frame structure of up link, the correlation of expression subframe, time slot, PUSCH and PUCCH.By the L1/L2 control signal of ul transmissions, in the situation that sends ascending physical signal shared channel (PUSCH), by distributing to the resource transmission of PUSCH, otherwise the resource transmission by the control signal special use.The former comprises the employed uplink scheduling information of PUSCH.The latter is known as ascending physical signal control channel (PUCCH:Physical Uplink Control Channel).The quality information of communicating downlink in the control channel of up link (CQI:Channel Quality Indicator) and physical down link sharing channel send to confirmation (ACK/NACK) etc.CQI is used for dispatch deal and adaptive modulation-demodulation and the coding processing (AMCS:Adaptive Modulation and Coding Scheme) etc. of the shared physical channel of down link.Positive response (ACK) that PDSCH that the content of sending to confirmation receives in the past by expression has suitably been received or represent one of them performance of the negative response (NACK) that it has not suitably been received.Although PUCCH bandwidth itself is very narrow, on one side owing to one side frequency hopping in subframe is transmitted, so can realize the high-quality that the frequency diversity effect is brought.
If what PUCCH was shared reduces with the roomy resource of then transmitting the shared data channel PUSCH of ascending physical signal, so from improving the viewpoint of throughput, PUCCH is little relatively good for the shared ratio of band system band.Many users of on the other hand, not transmitting the shared data channel PUSCH of ascending physical signal must pass through this PUCCH transmission CQI and ACK/NACK.Thereby from can report rapidly the viewpoint of CQI and ACK/NACK to the base station, the Radio Resource that preferred PUCCH uses is more.Therefore, must make a lot of users can utilize efficiently PUCCH, but in PUCCH, specifically how shining upon CQI and ACK/NACK as far as possible, and multiplexing a plurality of user how, as if fully do not study.

＜based on the orthogonal multiplex method of the cyclic shift amount of CAZAC sequence 〉
In PUCCH, in multiplexing a plurality of users' the situation, consider multiple multiplexing method.Wherein, from guaranteeing many user's multiplexing numbers and keep the strong viewpoints such as orthogonality that two methods are likely.One is the orthogonal multiplex method of using orthogonal code sequence (the permanent width of cloth zero auto-correlation code sequence), an orthogonal multiplex method that is based on the piece spread spectrum code sequence.
Fig. 3 represents to utilize the orthogonal multiplex method of the cyclic shift amount of the permanent width of cloth zero auto-correlation (CAZAC:Constant Amplitude Zero Auto Correlation) code sequence.As everyone knows, the permanent width of cloth of code length L zero auto-correlation code sequence C AZAC#1 (Δ=0) and should the perseverance width of cloth zero auto-correlation code sequence cyclic shift Δ (the sequence C AZAC#1 (Δ=Δ) of 1≤Δ≤L-1) obtain is mutually orthogonal.Thereby, the permanent width of cloth of code length L zero auto-correlation code sequence C AZAC# 1 and the sequence that is obtained by cyclic shift by this sequence: CAZAC#1 (Δ=0), CAZAC#1 (Δ=1), CAZAC#1 (Δ=2) ... (Δ=L-1) forms L orthogonal code sequence group to CAZAC#1.But different from common orthogonal code sequence, the sequence after certain yard sequence of the permanent width of cloth of code length L zero auto-correlation code sequence C AZAC# 1 and code length L multiplies each other has not illustrated the character as the permanent width of cloth zero auto-correlation code sequence.But, if only be that the zero auto-correlation code sequence C AZAC# 1 integral body of the permanent width of cloth of code length L multiply by a factor, then do not lose as the character of the permanent width of cloth zero auto-correlation code sequence.
In example shown in Figure 3, sequence is identical but the permanent width of cloth that the cyclic shift amount is different zero auto-correlation code sequence C AZAC#1 (Δ=Δ
A) and CAZAC#1 (Δ=Δ
B) be assigned to user A (UE_A) and user B (UE_B).The a corresponding permanent width of cloth zero auto-correlation code sequence of units chunk, for example 12 symbol units of component unit piece join with the permanent width of cloth zero auto-correlation code Serial relation of code length 12.

＜based on the orthogonal multiplex method of the permanent width of cloth zero auto-correlation code sequence and piece spread spectrum code sequence 〉
Also can make up about the orthogonal multiplex method of the permanent width of cloth zero auto-correlation code sequence of the use of Fig. 3 explanation and the orthogonal multiplex method based on the piece spread spectrum code sequence that illustrates about Fig. 4.
Fig. 5 represents the example of such combination.Employed identical among symbol among the figure and Fig. 3 and Fig. 4.The more than one factor performance of control information (being ACK/NACK among Fig. 5) by units chunk integral body be multiply by.Like this, except the orthogonality based on the permanent width of cloth zero auto-correlation code sequence, also can bring into play the orthogonality based on the piece spreading code, can the simpler and in high quality separation with each user's signal.Its result can further realize the high quality of the control information transmitted.
＜suitable orthogonal multiplex method 〉
Fig. 6 is illustrated in the employed orthogonal multiplex method of multiplexing a plurality of users' signal among the PUCCH.As mentioned above, confirmation ACK/NACK and/or channel condition information CQI are sent in main transmission in PUCCH.
Sending to confirmation ACK/NACK and represent whether the downlink physical shared channel that receives is in the past suitably received, is the information of particular importance in retransmitting control.Retransmit control the throughput of system is directly brought very large impact, so wish as far as possible in high quality transmission.On the other hand, send to confirmation and show by one of them of positive response (ACK) or negative response (NACK), can show by 1 bit in essence.Thereby, improve the error correction coding gain with the increase redundancy and compare, perhaps strengthen this point of orthogonality and can expect high-quality.For such viewpoint, in the present embodiment, for the multiplexing method of the user who sends to confirmation ACK/NACK, use will be based on the orthogonal multiplex method of the cyclic shift amount of the permanent width of cloth zero auto-correlation code sequence with based on the orthogonal multiplex method of piece spread spectrum code sequence and the method (Fig. 5) of usefulness.
The multiplexing method of the user of channel condition information CQI is distinguished according to the width of band system band and is used based on the multiplexing method of piece spread spectrum code sequence with based on the multiplexing method of the permanent width of cloth zero auto-correlation code sequence.This point does not differ widely with not considering the method in the past that such differentiation is used.
Generally in the situation of the information of the many bits of transmission, from the viewpoint of the coverage that increases the residential quarter, the large side of coding gain of preferred error correction coding.If this is because error correction coding gain then reaches the required transmitted power of required quality greatly can be lacked, if but the error correction coding gain is little, if then do not send with stronger power then do not reach required quality.Therefore come comparison based on the multiplexing method of the permanent width of cloth zero auto-correlation code sequence with based on the multiplexing method of piece spread spectrum code sequence from the viewpoint of error correction coding gain.
In based on the situation of the multiplexing method of the permanent width of cloth zero auto-correlation code sequence (Fig. 3), channel condition information CQI is by the factor performance of multiplying each other with units chunk.The units chunk number that can be used for transmission CQI has 5 at a time slot, has 10 in a subframe.Thereby, can utilize 10 factor (d
1..., d
10) transmit certain CQI.If with a factor corresponding to 2 bits (situation of QPSK mode), then subframe can use 10 * 2 bits /=20 bits.
In based on the situation of the orthogonal multiplex method of piece spread spectrum code sequence (Fig. 4), channel condition information CQI is showed by the symbol units in the units chunk.In the time slot a kind of units chunk is only arranged, contain two kinds of units chunk (the units chunk number is 10, but contains 5 units chunk of 2 groups of same contents) in the subframe.Owing to contain 12 symbol units in a units chunk, 2 kinds * 12/units chunk=24 symbol units can be used for performance CQI.With above-mentioned same, if with a symbol units corresponding to 2 bits (situation of QPSK mode), then subframe can use 24 * 2 bits /=48 bits.
Suppose to need 10 bits to show the value of CQI, then in the situation based on the multiplexing method of the permanent width of cloth zero auto-correlation code sequence, coding gain is 20/10=2.0.In the situation based on the multiplexing method of piece spread spectrum code sequence, coding gain is 48/10=4.8.Thereby, in the situation of such numerical example, from the viewpoint (or viewpoint of raising reliability) of coding gain, be favourable based on the orthogonal multiplex method of piece spread spectrum code sequence.
On the one hand, in the situation based on the orthogonal multiplex method of piece spread spectrum code sequence, if subframe structure is identical, each user's signal mutually orthogonal ((a) of Fig. 4 and (b), or (c) and (d)) then.But in the different situation of subframe structure, each user's signal can not become mutually orthogonal relation ((a) of Fig. 4 and (d), or (b) and (c)).This point is from different based on the multiplexing method of the permanent width of cloth zero auto-correlation code sequence.Thereby, in the situation based on the orthogonal multiplex method of piece spread spectrum code sequence, had better not transmit simultaneously with same frequency the signal of different subframe structures.Therefore, in the present embodiment, shown in Fig. 7 right side, preparation is used for the time slot that use is transmitted the time slot of CQI based on the orthogonal multiplex method of piece spread spectrum code sequence and is used for transferring ACK/NACK respectively, and they can not transmitted in same frequency simultaneously.
On the other hand, because system bandwidth is not fixing at all regions (area), so also there is narrow area in the wide area of existing system bandwidth.Thereby, wide to can be in PUCCH preparing respectively to be used for the time slot of transmission CQI and being used in the situation of degree of time slot of transferring ACK/NACK preferred above-mentioned so multiplexing method in system bandwidth.But, the time slot of using in order in PUCCH, to prepare respectively time slot that CQI uses and ACK/NACK, shown in Fig. 7 right side, must for example guarantee specially about the frequency band of 2 Resource Block be used for PUCCH.
If all number of resource blocks that comprise in the band system band have 25 as Fig. 7 right side, though then will be wherein two distribute to PUCCH, the resource that ascending physical signal is shared data channel PUSCH can significantly not reduce yet.But the whole number of resource blocks that perhaps comprise in the band system band like that only have six shown in Fig. 7 left side.If distribute to PUCCH with two in six Resource Block, then all the resource of the 2/6=1/3 of frequency bands is assigned to PUCCH, if then very undesirable from realizing that ascending physical signal is shared the viewpoint of throughput of data channel.
Therefore, in the present embodiment, in the narrow situation of system bandwidth, the user's of transmission CQI signal uses the permanent width of cloth zero auto-correlation code sequence multiplexing.As mentioned above, in the multiplexing method based on the permanent width of cloth zero auto-correlation code sequence, even subframe structure is different, also can each user's signal in orthogonal is multiplexing, so shown in Fig. 7 left side, they can be sent simultaneously in identical dedicated frequency band.Thus, in 6 Resource Block, can only distribute a Resource Block to PUCCH.Can be wide or narrow by suitable any method decision systems band.For example, also can pass through system bandwidth and a certain threshold, thus width and the orthogonal multiplex method of affirmation system bandwidth.
According to above-mentioned discussion, distinguish so as shown in Figure 6 the orthogonal multiplex method of using.But above-mentioned discussion about coding gain depends on subframe structure and units chunk structure.If with more vague generalization of above-mentioned discussion, then also can count N according to the units chunk in the subframe
Block, the timeslot number N in subframe
Slot, the component unit piece system unit count N
ElementCorrelation and distinguish the orthogonal multiplex method of the signal that uses transmission CQI.For example, if
N
Block＜N
slot×N
element
Then as shown in Figure 6, in the wide situation of band system band, the preferred orthogonal multiplex method of using based on the piece spread spectrum code sequence.Above-mentioned numerical example satisfies this relational expression (10＜2 * 12).Otherwise, if
N
Block＞N
slot×N
element
Then perhaps use is better based on the orthogonal multiplex method of the permanent width of cloth zero auto-correlation code sequence with the width of band system band is irrelevant.For example, count N at the system unit of component unit piece
ElementNot 12 but in 4 the situation, become such relation (10＞2 * 4).
System unit at the component unit piece is counted N
ElementIn 5 the situation since from the viewpoint of coding gain regardless of quality, so preferably decide the orthogonal multiplex method according to other viewpoint.
